Il designer 24 ° Studio, is the winner of the 2011 Shitsurai International Art Competition. Crater Lake is an environmental installation that serves as a meeting place with friends, where you can contemplate your surroundings, or just sit for a moment. The design was inspired by the social revitalization of the city of Kobe, Japan after the Great Hanshin-Awaji earthquake of 1995. Multiple ideas and materials were tested to realize the complexity of the smooth and wavy shape. Wood was chosen
for its strong structural capacity, the ease with which to work it, and the natural qualities. One of the main problems was the expression of the continuous and smooth surface without using expensive techniques. The solution was to divide the circular surface into a number of radial parts, in the optimal number of 20 parts. The factors that determined this optimal number were, overall surface expression, manufacturing process, and method of transportation.
